Description

CROSS-REFERENCE TO RELATED APPLICATION

The present application claims priority to PCT Patent Application No. PCT/CN2016/090024, filed to China Patent Office on July 14, 2016 , entitled "Communication Method, Base Station and User Equipment". The features of the preamble of the independent claims are known from WO2007/014025A2 , US2011/090810A1 and WO2013123980A1 .

TECHNICAL FIELD

The disclosure relates to the field of communications, and in particular to a communication method and a User Equipment (UE).

BACKGROUND

In an existing mobile communication system, after a base station allocates an uplink resource to a UE, the UE needs to take a certain processing time, and then uses the uplink resource to transmit data. For example, in a Long Term Evolution (LTE) system, the base station allocates an uplink resource to the UE at a subframe time n, and the UE uses the allocated uplink resource for uplink data transmission at a subframe n+4. In the LTE system, the duration of a subframe is 1ms, so that a UE processing time in the LTE system is 3ms. In other words, a processing time required for data transmitting by the UE cannot be less than 3ms. In the LTE system, not only an uplink scheduling time is in the form of n+4, but also an uplink retransmission preparation time is also in the form of n+4. Therefore, the scheduling timing of the system is closely related to the UE processing time. It is generally considered in the prior art that the processing time of different UEs is a fixed value (such as 3ms), and system scheduling is performed based thereon.
With the development of communication technologies, e.g., in a 5th Generation (5G) system, numerologies of different UEs may be different from each other, highest UE categories supported by different UEs may be different, processing capabilities of different UEs may also be different, and the above situation may cause different UE processing time between different UEs or different UE processing time under different configurations of the same UE, thereby affecting system scheduling.

SUMMARY

The present invention is defined in the independent claims. The disclosure provides a communication method and a UE, intended to improve the communication performance.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the disclosure are clearly and completely described below in combination with the accompanying drawings in the embodiments of the disclosure. It is apparent that the described embodiments are a part of the embodiments of the disclosure, and not all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the disclosure without paying any creative work shall fall within the scope of protection of the disclosure.

In the embodiments of the disclosure not covered by the claimed invention, the terms "network" and "system" are often used interchangeably, but those skilled in the art can understand the meaning thereof. The UE involved in the embodiments of the disclosure not covered by the claimed invention may include various handheld devices, in-vehicle devices, wearable devices and computing devices having a wireless communication function, or other processing devices connected to a wireless modem, and various forms of UEs, Mobile Stations (MSs), terminals, terminal devices, and the like. For convenience of description, in the embodiments of the disclosure not covered by the claimed invention, the devices mentioned above are collectively called UEs.
The network device in the embodiments of the disclosure not covered by the claimed invention may be a device for communicating with a terminal device. The network device may be a Base Transceiver Station (BTS) in a GSM or a CDMA, or a NodeB (NB) in a WCDMA system, or an Evolutional NodeB (eNB or eNodeB) in an LTE system, or a wireless controller in a Cloud Radio Access Network (CRAN) scenario. Or, the network device may be a relay station, an access point, an in-vehicle device, a wearable device, and a network device in a future 5G network or a network device in a future evolved Public Land Mobile Network (PLMN). The embodiments of the disclosure are not limited.
FIG. 1 is a schematic diagram of an application scenario of a communication method according to an embodiment of the disclosure. As shown in FIG. 1, the application scenario includes a network device and a UE, wherein the network device and the UE communicates through a wireless link.
In order to improve communication performance, the disclosure provides a communication method, a network device and a UE. It may be used to transmit one or more UE processing times supported by the UE to the network device, so that the network device performs system scheduling or other related operations according to the reported UE processing time, and the communication performance can be improved.
FIG. 2 shows a communication method 200. The method 200 is performed by a UE. The method 200 includes the following operations.
At S201, a UE generates processing time information, the processing time information indicating one or more UE processing times supported by the UE.
The UE processing time is time required for the UE to process data during the communication process. For example, the UE processing time may be time for preparing data uplink transmission after the UE receives an uplink scheduling instruction of the network device; or the UE processing time may be time for completing downlink data reception (completing channel decoding) after the UE receives a downlink scheduling indication of the network device.
Alternatively, in the embodiment of the disclosure not covered by the claimed invention, the UE may directly report the one or more UE processing times supported by the UE, or may report one or more levels corresponding to the one or more UE processing times supported by the UE. For example, at least one UE processing time level may be defined, and the at least one UE processing time level may have a correspondence with at least one UE processing time range. The UE may report the UE processing time level corresponding to the UE processing time range covering the UE processing time(s) supported by the UE. The network device may notify the UE of the manner of classifying the UE processing time levels by means of signaling (such as dedicated signaling or broadcast signaling), or the network device may preset the manner of classifying the UE processing time levels in a protocol with the UE.
Alternatively, the UE may report a minimum UE processing time supported by the UE through the processing time information, or may report at least one UE processing time supported by the UE. The UE may report a UE processing time level corresponding to a minimum UE processing time supported by the UE through the processing time information, or may report at least one UE processing time level supported by the UE. The UE processing time level corresponding to the minimum UE processing time may be a UE processing time level corresponding to a UE processing time range covering the minimum UE processing time. Those skilled in the art can understand that if the UE can support a certain UE processing time level, the UE can support another UE processing time level lower than the UE processing time level.
The UE also report the processing time information according to a processing time corresponding to a target parameter supported by the UE, the target parameter including a target numerology and the UE processing time being time required for data processing in case that the UE configures the target parameter, wherein the target numerology comprises subcarrier spacing.
The target parameter may further comprise any one of a target UE category or a target carrier bandwidth. The target UE category, the target numerology and the target carrier bandwidth are some UE categories, some numerologies and some carrier bandwidths supported by the UE, or all UE categories, all numerologies and target carrier bandwidths supported by the UE. The disclosure does not make any limitation on this. The UE transmits the processing time information to the network device, so that the network device schedules the UE or the system according to the UE processing time corresponding to the target parameter, or may perform other related operations according to the UE processing time.
Alternatively, the above UE category may be the UE category. It is to be noted that in a communication system, the UE category may be used to define a maximum uplink and downlink transmission rate that can be supported by the UE. Or, the UE category is used to classify the terminal rates (levels) of the UE. A given UE category is related to a certain Carrier Aggregation (CA), Multiple-Input Multiple-Out (MIMO) and highest modulation (such as 64QAM and 256QAM). The above CA, MIMO and highest modulation may all affect the size of the processing time of the UE. Therefore, the UE processing time corresponding to different levels of UE categories is different. In addition, as the UE category is higher, the maximum uplink and downlink transmission rate that can be supported is higher. For example, if the highest UE category of a UE is N, all rates from UE category 1 to UE category N can be supported, and the highest rate that can be supported is determined by UE category N. In addition, it is to be noted that UE category 0 is also written in the standard of 3GPP Rel. 12, which can be dedicated to the Internet of Things and is used to indicate the maximum uplink and downlink transmission rate of a Machine Type Communication (MTC).
Furthermore, in addition to the above CA, MIMO and highest modulation, the UE processing time is affected by many other factors. For example, in the 5G discussion, numerologies corresponding to different UEs may be different, or the same UE may support multiple numerologies, and different numerologies may also affect the size of the UE processing time. The numerology may also be called a basic parameter set, which may be the most basic parameters of a communication system (such as a cellular system). For example, for an LTE system or a 5G system, the numerology includes a subcarrier spacing, a symbol duration and the like of the system. The subcarrier spacing and the symbol width may also affect the size of the processing time. In other words, for different numerologies supported by the UE, the UE processing time corresponding to the same UE category may also be different.
In addition, carrier bandwidths supported by different UEs may be different, or the same UE may support multiple carrier bandwidths, and carrier bandwidths supported by the UE may be different, which may also affect the size of the UE processing time.
At S202, the UE transmits the processing time information to a network device.
The UE reports processing time information to the network device, the processing time information indicates one or more UE processing times supported by the UE, so that the network device performs scheduling or other operations on a system based on the processing time information, thereby improving the communication performance.
Alternatively, in the method 200, the processing time information includes a minimum UE processing time supported by the UE.
In the embodiments of the disclosure not covered by the claimed invention, the UE may directly report the minimum UE processing time supported by the UE to the network device, so that the network device performs related scheduling or other operations, thereby improving the communication performance.
Alternatively, in the method 200, the UE supports at least one UE processing time level, the at least one UE processing time level has a correspondence with at least one UE processing time range, and the processing time information includes at least one UE processing time level supported by the UE.
Alternatively, in the method 200, the UE supports at least one UE processing time level, the at least one UE processing time level has a correspondence with at least one UE processing time range, and the processing time information includes a UE processing time level corresponding to a minimum UE processing time supported by the UE.
For example, the processing time of the UE may be classified into three levels:

Level 1: 3ms and above;
Level 2: 0.5ms to 3ms;
Level 3: 0.1ms to 0.5ms.

If the minimum UE processing time that can be supported by the UE is 0.3ms, a level corresponding to the minimum UE processing time is 3. It is indicated that the UE can support three UE processing time levels namely Level 1, Level 2, and Level 3. The UE may indicate, in the processing time information, that UE processing time levels supported by the UE are Level 1, Level 2, and Level 3. Or, the UE may indicate, in the processing time information, that the UE processing time level corresponding to the minimum UE processing time supported by the UE is Level 3.
Alternatively, the UE may preset a manner of classifying the UE processing time levels by using a protocol with the network device, or may notify the UE of a manner of classifying the UE processing time levels by the network device. For example, in the method 300, the UE may receive notification information from the network device, the notification information indicating a correspondence between at least one UE processing time level and at least one UE processing time range. Alternatively, the notification information may be dedicated signaling or broadcast signaling.
Alternatively, the UE may actively report the processing time information to the network device. For example, the UE may report the processing time information to the network device when the base station/network is accessed for the first time, and the UE may report the processing time information after the network device instructs the UE to report the UE processing time.
For example, the method 300 further includes the following operations.
At S203, before the UE generates the processing time information, the UE receives an indication message from the network device, the indication message being configured to instruct the UE to report one or more UE processing times supported by the UE.
In the embodiments of the disclosure not covered by the claimed invention, the UE may receive an indication message from the network device, the indication message being configured to instruct the UE to report the supported UE processing time, thereby improving the communication performance.
Further, the indication message may indicate a manner in which the UE reports the UE processing time. For example, the indication message may instruct the UE to report a minimum UE processing time supported by the UE, or instruct the UE to report a UE processing time level corresponding to the minimum UE processing time supported by the UE, or instruct the UE to report at least one UE processing time level supported by the UE. The embodiment of the disclosure does not make any limitation on this.
The UE also report a UE processing time according to a target parameter supported by the UE. For example, in the method 300, not falling within the scope of the claims, the processing time information reported by the UE further include the UE processing time corresponding to the target parameter, the target parameter being at least one of the following parameters: a target UE category, a target numerology or a target carrier bandwidth, and the UE processing time being time required for data processing in case that the UE configures the target parameter.
In the disclosure, the UE reports processing time information to the network device, the processing time information indicates a UE processing time corresponding to the target parameter supported by the UE, so that the network device performs scheduling or other operations on a system based on the processing time information, thereby improving the communication performance.
Alternatively, the method 200 further includes the following operations.
At S204, before the UE generates the processing time information, the UE receives an indication message from the network device, the indication message including first information configured to instruct the UE to report a UE processing time corresponding to the target parameter.
In the embodiments of the disclosure not covered by the claimed invention, the UE may receive an indication message from the network device, and first information included in the indication message may be used to instruct the UE to report a UE processing time corresponding to a target parameter, thereby improving the communication performance.
Alternatively, the indication message may be used to instruct the UE to report the UE processing time(s) supported by the UE.
In the embodiments of the disclosure not covered by the claimed invention, the network device may configure a manner in which the UE reports the UE processing time by the indication message, or the network device may instruct the UE to report the UE processing time corresponding to specific target parameters or specific combination of target parameters. The UE may generate processing time information based on the indication message, and transmit the processing time information to the network device.
Alternatively, as an embodiment, not falling within the scope of the claims, the processing time information includes a UE processing time corresponding to a combination of target parameters, the combination of target parameters including at least two of the following parameters: the target UE category, the target numerology, or the target carrier bandwidth.
Alternatively, as an embodiment not covered by the claimed invention, the network device may indicate, in the indication message, the range of the UE category, the numerology and/or the carrier bandwidth reported by the UE. For example, the network device may indicate UE category 3, UE category 5 and UE category 7 in the indication message, and the UE may merely report the UE processing time corresponding to the three UE categories to the network device by the processing time information. For example, the network device may configure a list of UE categories for the UE, and the UE may merely report UE processing times corresponding to the UE categories included in the list. The network device may transmit the list through the indication message. It should be understood that the highest UE category that can be supported by the UE may exceed the highest UE category that the network device requires the UE to report. However, when the highest UE category that the network device requires the UE to report exceeds the UE category that can be supported by the UE, the UE may merely report the UE processing time corresponding to the UE category that can be supported by the UE. Similarly, the range of the numerology or carrier bandwidth supported by the UE may exceed the range that the network device requires the UE to report. However, when the range of the numerology or carrier bandwidth that the network device requires the UE to report exceeds the range supported by the UE, the UE may merely report the UE processing time corresponding to the numerology or carrier bandwidth supported by the UE.
Alternatively, as an embodiment not covered by the claimed invention, the indication message may include second information, the second information being configured to instruct the UE to report a UE processing time corresponding to a UE category that is less than or equal to a highest UE category. After receiving the indication message, the UE may determine, from the UE categories supported by the UE, a UE category that is less than or equal to the highest UE category, determine the UE category that is less than or equal to the highest UE category as the target UE category, and then generate processing time information. For example, the network device may configure the UE to report different UE processing times corresponding to UE category 1 to UE category N. For example, if the highest UE category required to be reported by the network device is UE category 7, the UE will report different UE processing times corresponding to UE category 1 to UE category 7.
Alternatively, as an embodiment, the target numerology may be M numerologies, and the processing time information may include a UE processing time, for each of the M numerologies, corresponding to the target UE category, where M≥ 1.
It is to be noted that the numerology may include the most basic parameters of a communication system (such as a cellular system). For example, for an LTE system or a 5G system, the numerology includes a subcarrier spacing, a symbol duration and the like of the system.
In the embodiments of the disclosure, the UE reports, through the processing time information, the UE processing time corresponding to the combination of different numerologies and the target UE category configured by the UE, so that the network device performs system scheduling or other operations according to the processing time information, thereby improving the communication performance.
The above M numerologies may be all of the numerologies supported by the UE, or may be some of the numerologies supported by the UE.
Alternatively, the network device may instruct the UE to report a UE processing time, for each of the M numerologies, corresponding to the target UE category. The indication may be included in an indication message, or may be included in other information.
For example, Table 1 indicates a manner in which the UE reports the UE processing time to the network device, and the UE may transmit the processing time information to the network device according to Table 1. Table 1 may be preconfigured for the UE by the network device. For example, the network device may indicate, to the UE by the indication information, that the UE is expected to report the range of the combination of the numerology and the target UE category. The UE may report the UE processing times, for all of the numerologies supported by the UE, corresponding to the target UE category, to the network device, or the UE may report the UE processing times, for some of the numerologies supported by the UE, corresponding to the target UE category, to the network device.

Alternatively, as an embodiment, the target carrier bandwidth may include N carrier bandwidths, and the processing time information may include a UE processing time, for each of the N carrier bandwidths, corresponding to the target UE category, where N is greater than or equal to 1.
The N carrier bandwidths may be all of the carrier bandwidths supported by the UE, or may be some of the carrier bandwidths supported by the UE.
Alternatively, the network device may indicate, to the UE, that the network device expects the UE to report a UE processing time, for each of the N carrier bandwidths, corresponding to the target UE category. The indication may be included in indication information, or may be included in other information.
For example, the UE may transmit the processing time information to the network device according to Table 2. Table 2 may be preconfigured for the UE by the network device. For example, the network device may indicate, by using the indication information, that the UE is expected to report the range of the combination of the carrier bandwidths and the target UE categories. Table 2

For another example, the UE may also transmit the processing time information to the network device according to Table 3. Table 3 may be preconfigured for the UE by the network device. For example, the network device may indicate, to the UE by using the indication information, that the UE is expected to report the range of the combination of the carrier bandwidths, the numerologies and the target UE categories. The UE reports, to the network device, the UE processing time, for each numerology under each carrier bandwidth supported by the UE, corresponding to the target UE category.
